ELTAZI Faculty of Agriculture, Omdurman Islamic University, P.O. Poult. Experimental Procedures . Broiler production at mass level has already been achieved and now emphasis is being laid on increasing meat quality by altering various characteristics of broiler meat. Broilers were group weighed and feed efficiencies calculated at 14, 28, and 42 days of age. The objective of this study was to determine if a diet supplemented simultaneously with vitamins C and E would alleviate the negative effects of heat stress, applied between 28 and 42 days of age, on performance, carcass and meat quality traits of broiler chickens. Performance and carcass quality of broiler chickens fed diet containing pineapple waste meal fermented by “ragi tape” J S Mandey*, B Tulung, J R Leke, B F J Sondakh Animal Husbandry Faculty, Sam Ratulangi University Manado, North Sulawesi, Indonesia *E-mail: [email protected] Abstract. All quality characteristics of carcass are inherent in the hybrids (genotype) and are therefore conditionally hereditary characteristics with precisely defined heritability proposed values (Chen et al., 1987). Unopened fractures, mean bruises located on the wing, thigh, or the filet are the main superficial lesions. In conclusion, broiler carcass scalding method did not have a significant impact on broiler fillet quality. Microbiological quality of broiler carcasses during slaughter processing ... Five broiler carcasses from each sampling point were collected (n = 20); a total of 160 broiler carcasses were analysed. INTRODUCTION . Immediately prior to slaughter, the selected broilers were weighe d. Upon slaughter and primary carcass processing, the processed carcasses were cooled in a cooling chamber for 24 hours at 0–4°C. This study aimed to determine the carcass and meat quality of broiler chickens based on the slaughter age (28, 30, 32, and 34 days). There are several procedures at the processing plant where a few simple checks can help to ensure carcasses are … E-Mail:[email protected] ABSTRACT Received at: 22/3/2014 Accepted: 12/4/2014 The effect of feeding broiler chicks diets containing different levels of ginger powder as natural feed additive on productive performance, carcass … Carcass are pieces of broiler without feathers, blood, head, neck, feet, claws, and internal organs. There are 3 types of lesions: superficial, intermediate and deep lesions. Key words: broiler, carcass, humoral immunity, yeast Introduction Many other beneficial factors of yeast inclusion such as improved carcass development and breast In recent years, there has been a great attention to yield were intensively reported.

Appl. carcass quality definition in English dictionary, carcass quality meaning, synonyms, see also 'carcase',Carcassonne',Caucasus',Caracas'. Animals . In conclusion broiler chicks could be stocked up to 20 birds/m. The broilers were slaughtered at day 35, the carcasses were weighed and the breast muscles were excised from 16 birds per each feeding group (two birds per replicate pens) and used for meat quality evaluation. carcass quality traits. Figure 1.2: Producing quality broiler meat - the total process. At 9, 14, 34 and 49 days, birds in group II showed a significantly greater body weight (p <0.05) than birds in group I (control). The carcass characteristics included live and car- cass weights, carcass rate, dressing rate, and retail cut weight. composition and carcass characteristics in broiler chickens. The altitude is between 300 and 600 meters above sea level and the mean annual temperature RESULTS AND DISCUSSION of 27°C with mean rainfall of 1247mm [15]. The aim of this study was to determine the effect of herbal feed additive on growth performance, carcass characteristics, the chemical composition of breast muscles and selected meat quality parameters in broiler chickens. Broiler carcass chilling method has a much greater impact on the quality of breast meat than scalding method, according to researcher based in Athens, Georgia, and the influence of chilling on breast meat quality was independent of scalding treatment. The mean separation was done by using Duncan’s multiple range test (Duncan, 1955). Percentage dry matter of the litter and a subjective evaluation of general litter conditions (moisture and caking) were scored weekly, with the percentage nitrogen and total quality of litter produced in each chamber measured at the conclusion of the study. Dressing percentage The per cent dressing yield under different treatment groups were recorded as 69.44±0.38, 69.19±0.38, 69.08±0.45, 68.74±0.55 and 67.96±0.36g for T 0, T 1, T 2, T 3 and T 4 groups, Feeding strategy in growing broiler chickens should be to produce animals with maximum lean body mass, highest feed conversion ratio and maximum body weight. Characteristics of lesions observed on broiler chickens carcasses: Each type of injury has been described in terms of its nature, its location and the degree of severity (Table 1). In fact, the revenue from chicken paws in 2008 alone was worth $ 280 million in the US. Several factors can contribute to how successfully broilers are eviscerated during poultry processing, and consequently the processing plant’s final yield. high quality broiler carcasses that will be acceptable for consumers; Acceptability depends on the quality and quantity of edible parts of carcasses, and the amount of muscle mass in carcass. All dietary treatments failed to exert any significant (P > 0.05) effect on various carcass parameters (dressing percentage, abdominal fat, giblet yields), serum protein and cholesterol concentrations, and meat quality parameters (water holding capacity and pH) of broiler chicken at 42 days of age. The three main steps and stages in the whole broiler production process are: • rearing and managing broiler breeders (i.e. Each sample was represented by the whole carcass, which was removed from the processing line. 1080 sexed chicks were provided with a common starter diet from 0-4 weeks of age. Carcass weight of broiler according to Soeparno (1994) is influenced by several factors, such as gender, ages, race, number and quality of feed, the slaughter weight and feed intake. Broiler or sometimes broiler-fryer is also used sometimes to refer specifically to younger chickens under 4.5 pounds, as compared with the larger roasters. Carcass Quality The carcass traits and their mean (±SE) values of broilers under different treatment groups are presented in Table 2. Carcass characteristics were affected by age and sex of chickens. However, broiler carcass chilling method significantly influenced meat lightness on the ventral side, water-holding capacity, and texture of breast fillets. Broilers will yield a dressed carcass weight of 70 to 75 per cent of their live weight. significant difference was observed in the SF of the birds in all the treatment with mean value ranging from 3.35% to 3.60%. This study is designed to evaluate the effects of different levels of Berberine (BBR) on carcass traits and meat quality of broilers fed diets contaminated with Aflatoxin B 1 (AFB) and Ochratoxin A (OCT). How to maintain broiler carcass quality during evisceration Ensuring the best possible evisceration starts with feed withdrawal, but comprises the proper completion of several processing activities. Res. Growth dynamics was investigated on 800 broilers and carcass quality traits (carcass weight, conformation, yields of major carcass parts and tibia quality) on sample of 80 carcasses differentiated according to gender of chickens. In experimental groups, dietary … In 2012, their mean price was set at 13.67 $ /kg making it the third most important chicken export revenue. 6 poultry processing tips to improve carcass quality Ensuring that key operations at the poultry plant are performed properly can help to ensure maximum output of high-quality birds. Enrich your vocabulary with the English Definition dictionary Growth performance, gut mucosal immunity, and carcass and meat quality of broilers in both groups were assessed after being reared for 49 days. Methods: A 42-day floor pen trial was performed with 288 Ross 308 broilers. More intensive growth of broiler in the group reared in lower stocking density, that is, intermittent light regime, was established. In addition some specific carcass parts such as paws have gained some economical interest. The experiment was performed on 1080 Ross 308 chickens, which were randomly divided into six groups with six replicates per group. E. Keywords: Stock density, vitamin E, carcass quality, broilers . The overall mortality rate recorded in this study was 7.8%. The mean body weights at the end of 7th and 8th weeks were 3.1 and 3.8 kg, respectively. Dietary lysine affects carcass quality and meat yield in broiler chickens. carcass traits, meat quality, and e ciency of the production of broiler chickens raised under thermoneutral and chronic heat stress conditions. Good poultry processing operations will keep rejects, partial or complete, to a minimum. Objective To determine the effect of dietary lysine level in the grower diet on broiler tissue composition. Carcass quality … Broilers carcasses are evaluated mainly through yield edible parts of which are expressed by dressing percentage (slaughter yields) and the quality of edible parts of carcass. The effect of strain and sex on carcass characteristics Experimental birds: A total bird of 300 day-old chick of is shown in Table 1. The broiler growing phase is one part of the integrated total meat production process, encompassing feed mills, parent stock farms, hatcheries, broiler farms, processors, retailers and consumers.
